Depends on which system...but for fun's sake we'll say that these all come out AFTER the Wii U has managed to find some moderate sales success and the 3DS has continued to dominate (especially after Pokemon X and Y came out). Let's also assume that all of the games receive above-average reviews and aren't half-assed.
Star Fox: Wii U-1.5-2 million (I think an epic, HD Star Fox game would sell) 3DS-1 million
Ice Climbers: Wii U-less than 250k 3DS-500k (just think it would appeal more at a lower price and to a younger handheld audience)
1080: Wii U-500k (Games like M&S Olympics have diminished the mainstream appeal of games like this) 3DS-less than 500k
Mother: Wii U-750k 3DS-1 million (High-quality RPGs have been doing well on 3DS)
F-Zero: Wii U-1 million 3DS-500k
Wave Race: Wii U-1 million 3DS-500k
